Python操作Excel文件怎么用openpyxl和pandas读写

pip install openpyxl

from openpyxl import Workbook

# 创建工作簿
wb = Workbook()
ws = wb.active

# 添加数据
data = [
    ['Name', 'Age', 'City'],
    ['Alice', 30, 'New York'],
    ['Bob', 25, 'Los Angeles']
]

for row in data:
    ws.append(row)

# 保存到文件
wb.save("example.xlsx")

from openpyxl import load_workbook

# 加载工作簿
wb = load_workbook("example.xlsx")
ws = wb.active

# 读取数据
for row in ws.iter_rows(values_only=True):
    print(row)

pip install pandas openpyxl

import pandas as pd

# 数据
df = pd.DataFrame({
    'Name': ['Alice', 'Bob'],
    'Age': [30, 25],
    'City': ['New York', 'Los Angeles']
})

# 写入 Excel 文件
df.to_excel("example.xlsx", index=False)

# 读取 Excel 文件
df = pd.read_excel("example.xlsx")

# 显示数据
print(df)

pip install pandas openpyxl

import pandas as pd
from openpyxl import load_workbook

def write_excel_with_pandas(file_name, data):
    """ 使用 pandas 写入 Excel """
    df = pd.DataFrame(data)
    df.to_excel(file_name, index=False)

def read_excel_with_pandas(file_name):
    """ 使用 pandas 读取 Excel """
    df = pd.read_excel(file_name)
    print(df)

def read_excel_with_openpyxl(file_name):
    """ 使用 openpyxl 读取 Excel """
    workbook = load_workbook(filename=file_name)
    sheet = workbook.active

    for row in sheet.iter_rows(values_only=True):
        print(row)

def main():
    # 文件名
    file_name = 'example.xlsx'

    # 数据
    data = {
        'Name': ['Alice', 'Bob'],
        'Age': [30, 25],
        'City': ['New York', 'Los Angeles']
    }

    # 使用 pandas 写入 Excel
    write_excel_with_pandas(file_name, data)

    # 使用 pandas 读取 Excel
    print("使用 pandas 读取 Excel:")
    read_excel_with_pandas(file_name)

    # 使用 openpyxl 读取 Excel
    print("\n使用 openpyxl 读取 Excel:")
    read_excel_with_openpyxl(file_name)
